Title: Automatic overfilling protection mechanism - has float actuating piston to cause pressure build up in stages
IPC: B67D7/36
Filed: 1977-02-04
Abstract: The mechanism is built into a tank filler pipe, and automatically prevents overfilling, being particular for an underground tank. It has a housing (1) screwed to the filler pipe, with a cylinder closed by a top cover and with openings (17) at the bottom, there being a space between it (3) and the housing. The rod (8) of a piston (4) working in the cylinder is coupled to a float (12) outside the housing. As the tank is filled, the openings are shut off by the piston moving downwards, causing a pressure to build up in stages in the passage (20) for the fluid between cylinder and housing. A double valve (16) is fitted in the housing wall above the cylinder, its inner valve (21) connected with the passage, acts as a drain valve. The outer valve (22) is actuated by the float, and acts as a stop valve.

Title: Pacemakers of low weight and method of making such pacemakers
IPC: H05K7/02
Filed: 1977-02-05
Abstract: A method of making a pacemaker which includes, in a container a subassembly of, a battery nested in an electrical converter serving to produce heart-pacing pulses. This subassembly is encapsulated in a mold in rigid, polyurethane foam of low weight and capable of protecting the encapsulated components from shock. The body formed by prepotting is generally ellipsoidal and is nested snugly in one of the sections of an ellipsoidal container. Another section of the container is welded to the one section along the congruent rims. Additional potting material is injected through the boards between the sides of the encapsulated body and the adjacent walls of the container. The encapsulated body is held firmly in the container without potting material between the top and bottom and ends of the body and the container. The potting material is injected through the hole in which the electrical feedthrough is subsequently welded. Alternatively, the pacemaker is formed by enclosing the subassembly between the parts of the container, welding the sections of the container, and injecting the foam through the opening in the container through which the output conductor passes.

Title: Web splicing apparatus
IPC: B65H19/18
Filed: 1977-03-22
Abstract: The system has two supply rolls (3, 4) next to which a movable joining device is arranged which has an idler roll (11), a web brake (34a, 34), a cutter and a joining roll (27a, 27). If the device is arranged next to the almost-unwound supply roll, the web brake (34a, 34) is actuated and the web is stopped. If the device is arranged next to the full supply roll, the web brake stops the web for severing and aligning until the join has been produced. The joining roll has projections for guiding a cutting tool. On the discharge side of the joining device, the idler roll (11) is arranged which interacts with a dancer roll (12) in order to keep the web under tension. After the join has been produced, the idler roll (11) can be driven in order to increase the tension of the web and to accelerate the web taken off from the full supply roll to the normal velocity.

Patent ES-468137-A1 (ES)
Title: Ohmic contact to aluminum-containing compound semiconductors
IPC: H01L21/285
Filed: 1978-03-22
Abstract: A consistently low resistance ohmic contact is made to an aluminum-containing compound semiconductor by a multilayer deposition and heat treatment process. The process includes the deposition of a transition layer on the semiconductor surface to be contacted and an overlying gold layer to provide external contact. The transition layer consists of aluminum and a shallow dopant element which may be deposited as successive layers or together. After the transition layer and the gold overlay are deposited, the composite is raised to a temperature at which the transition layer is liquid. In cases in which the gold-dopant binary system has a polyphase region, it is preferable to select the thickness of the gold layer such that the gold-dopant alloy is in the solid solution region of the phase diagram of that binary system, to prevent enhanced diffusion to the upper gold surface along grain boundaries. In an exemplary realization, an Al-Sn layer was used to contact n-type GaAlAs.
Patent ES-468155-A1 (ES)
Title: Electronic ignition timing system using digital rate multiplication
IPC: G06F7/68
Filed: 1978-03-22
Abstract: An electronic ignition timing system for an internal combustion engine which rotates a crankshaft is disclosed. The ignition system comprises a plurality of variable engine condition sensors which produce corresponding analog output signals and a crankshaft position sensor. A timing control logic circuit periodically multiplexes each of the variable engine condition sensors such that they are sequentially connected as inputs to an analog to digital (A/D) converter which produces an output signal comprising a pulse train for each of the multiplexed engine conditions. The total number of pulses in each pulse train is related to the magnitude of the variable engine condition currently being connected to the A/D converter. In addition, high resolution crankshaft position pulses are produced, preferably by an electronic angle divider which receives coarse crankshaft position pulses and produces high resolution crankshaft position pulses. The variable engine condition pulse trains and the high resolution crankshaft position pulses are then multiplexed to produce an input signal to a binary rate multiplier (BRM) which has its output connected to a counter. The input signal going to the BRM is monitored by a separate counter which controls the output of a read only memory (ROM) that determines the multiplication factor M of the BRM. The use of this separate counter to monitor the inputs of the BRM results in producing an output count from the BRM which is a non-linear function of the input signal, and this is accomplished with the use of a minimum number of memory cells in the ROM. A count related to the output count of the BRM for all of the multiplexed inputs is loaded into a phase counter which then proceeds to count down at a rate determined by the high resolution crankshaft position pulses. A latch circuit is then used to generate a spark timing signal when the count of the phase counter reaches a predetermined count. The spark timing pulses are produced at predetermined engine crankshaft positions related to the output count of the BRM wherein the output count is the summation of a plurality of non-linear output functions relating engine spark timing to the plurality of multiplexed variable engine conditions, including engine speed.

Title: Pumping system to dispense several litres per hour - partic. of food prod. ingredient or chemical dosing additive
IPC: G01F11/04
Filed: 1979-11-07
Abstract: Pumping system for dispensing small quantities of fluid, e.g. 2-3 litres per hour of a food prod. ingredient or chemical additive comprises a multiway solenoid valve operated by a cycle timer. The valve first opens a passage which allows fluid to flow from a source of supply into a pumping cylinder by displacing a piston. The valve is then switched to allow the cylinder to be emptied into a delivery line by return of the piston. The return of the piston can be by relaxation of a loaded spring or by fluid being directed onto the other side of the piston which is double-acting. The cycle time is pref. regulated and the displacement of the piston adjusted. The system cannot overfeed.
